COTTON GIN.

Application led December 1.4, 192,5. Serial No.V 75,427.

This invention relates to new and useful improvements in a cotton gin.

One object of the invention is to produce an attachment for a gin whereby the trash and motes may be more effectively separated from the lint.

Anotherobject of the invention is to provide an attachment. of the character describedl which is so disposed relative to the gin saws, that it will not interfere with the passage of the motes and diit to the conveyor for them, but will deflect the lint, which has a tendency to pass, by centrifugal force, with said motes into the mote conveyor and direct the same into .the lint flue through which it passes into the lint conveyor.

A further feature of the invention resides in the provision of an attachment of the character described which is of very simple constructionand may be. cheaply and easily produced and readily applied to any conventional type of gin,.either of the brush type or of the pneumatic type.

lVith the above and other objects in view this invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 shows a fragmentary rear view of the gin, showing the breast partly broken away to disclose the attachment in its relation to the saws, and

Figure 2 shows a vertical cross sectional view thereof.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures the numeral 1 .designates the gin stand, as a whole, mounted on which is the enclosing body, or casing 2. Rotatably mounted in the casing there is avsaw shaft 3 fixed on which are the saws 4, spaced the required distance apart. The seed cotton is fed to the saws through the hopper 5, from an overhead conveyor (not shown).` These rapidly rotating saws in cooperation with the intervening ribs 6 strip the lint from the seed and the seed passed down through the chute 7. The lint is carried on around by the saws teeth and is freed from said saws by an air blast delivered against said saws,- at their rear, through the long air blast nozzle 8 in which the air duct 9 terminates.

This ductcommunicates with the air chamber 10 arranged behind the gin. The nozzle 8 is downwardly turned in the direction of the rotation of the saws and the air blast frees the lint from the saws and carries it through the lint duct 11 to the main lint flue 12and it passes thence to the condenser.

The metes, vdirt and trash, being heavier than the lint are separated from the lint hy centrifugal force at the moting point. 15, near the top Vof the saws, and over the nozzle 8 andv into the mote conveyor 14k.

The parts hereinabove described are common to the pneumatic type of cotton gin7 and now in common use. This. type of gin, however, is defective in that a certain part of the lint passes by centrifugal forcealong with the motes into the mote conveyor and is wasted. The attachment presently tobe described has beenv designed to catch this lint, which would otherwise pass with the.

motes, and divert it back into the lint duct 11. To accomplish this purpose there is provided a deflector plate 15 which is disposed in the rear of and spaced from the saws This plate extends from end to end of the gin breast and at its upper edge is swung from a rod whose ends 16, 16, work through aligned bearings in the ends of the gin breast and are retained in place by the nuts 17, 17. The lower edge of this deflector plate overlaps and hangs in the rear of the nozzle end of the duct 9. The lint, which has a tendency to pass, by centrifugal force, with the motes, being somewhat lighter than said motes, will lag behind them and the deflector plate is positioned so as to catch this lagging lint but to permit the motes, dirt and trash to pass over into the conveyor 14. The inner side of the deflector board has a lengthwise declining shield 18 on its inner side which fits over the nozzle end of the air duct 8 and prevents the congestion of the deflected lint thereon.

lVhatI claim is: Y

1. In a cotton gin the combination with the saw, the air duct and the lint ductthereof, of a deflector disposed on substantially a vertical plane and spaced behind said saws and arranged above the nozzle end of said air duct, said deiiector being pivoted to swing about a transverse axis with its lower end free.

2. In a cotton gin the combination with the saws, the air duct and the lint duct thereof, of a deflector spaced behind said saws and arranged above the nozzle end of said air duct, said deiiector hanging in substantially a vertical plane and extending from end to end of the gin breast with its lower edge free and overlapping the nozzle end of said air duct in 'the rear.

3. In a cotton gin the combination with the saws, the air duct and the lint duct thereof, oi? a delector swung in substantially a vertical plane and spaced behind said saws and arranged above the nozzle end of said air duct and a lengthwise shield on the inner side of said defiector and litting over the adjacent end of said air duct, the lower edge of the deliector being` 'tree and being held by gravity against the rear side of said nozzle.

t. In a cotton gin the combination with the saws and the blast air nozzle thereof, of a delector depending in substantially a vertical plane and spaced behind the saws and above said nozzle and extending from end to end oi the gin breast and having its ends pivotally anchored to the ends of said breast, with its lower edge 'free and resting by gravity against the rear of said nozzle.

5. In a cotton gin the coinbination with the saws and the blast air nozzle thereof, of a deector disposed in substantially a vertical plane and spaced behind the saws and above said nozzle and extending troni end to end of the gin breast and having its ends anchored to the ends of said breast, so that the de'iector will swing about a horizontal axis, said deiiector having its lower end free, a declining shield carried by said delector and disposed over said nozzle.

G. In a cotton gin the combination with the saws and the blast air nozzle thereof, of a de'tlector swung in substantially a vertical plane and spaced behind the saws and above said nozzle and extending from end to end oi' the gin breast and having its ends pivotally anchored to the ends of said breast so that the deflector will swing about a horizontal axis with its lower edge free and resting against the rear of the nozzle a lengthwise shield on the side of said delector facing the saws and disposed over said nozzle- 7, An attachment for cotton gins comprising a substantially rectangular detiector plate, a lengthwise shield carried by one side of said plate, and outwardly extending end studs carried by said plate above the central horizontal line of the plate.

In testimony whereof I have signed my naine to this speciication.
